Juliette Cornileau: Woman FIDE Master & Blitz Enthusiast
Known online as keopki, Juliette Cornileau has carved out a fierce reputation in the world of online chess, proudly holding the title of Woman FIDE Master. With a style characterized by gritty resilience and an uncanny knack for comebacks (a staggering 85.66% comeback rate, no less!), Juliette dominates the 64 squares with a blend of calculation and psychological warfare.
Rating Rollercoaster & Playing Style
Juliette’s peak blitz rating soared to an impressive 2266 in July 2024, showcasing her rapid tactical prowess and strategic mastery. Her bullet rating isn’t far behind, hitting a crisp 2092 in May 2025, proving she’s just as lethal under the ticking clock. Rapid games? She’s got those covered too, with a peak around 2069.
Her approach to blitz involves patience — she averages about 63 moves per win, suggesting she’s willing to outlast opponents in long tactical battles rather than relying solely on quick-fire attacks. Interestingly, she wins slightly more often when playing with the black pieces (48.26%) than with white (46.48%). A sneak peek into her psychological game reveals a modest tilt factor of 9, meaning even when the going gets tough, she keeps her cool — most of the time.
Opening Repertoire: A Secret Weapon
Juliette’s openings hint at a playful, yet solid repertoire. She plays a lot of “Top Secret” (read: unpredictable) moves – 270 games and counting – with a respectable 40.74% win rate in blitz. She doesn’t shy away from classic defenses, including the Caro-Kann (with an even 50% win rate), the Queen’s Gambit Declined, and the English Opening, all showcasing her well-rounded knowledge.
Battle-Tested: Recent Games
Her latest victory was a slick win using the Philidor Defense, forcing her opponent to resign after just 18 moves in a dramatic clash full of tactical fireworks. Even in defeat, Juliette keeps her head high — a recent loss came in a tense battle against a time scramble, reminding us that in bullet chess, every millisecond counts (and sometimes slips away!).
Did You Know?
- She’s got an impressive longest winning streak of 10 games — a true streak of brilliance.
- Despite the setbacks, Juliette remains a fierce competitor with a stubborn streak: her longest losing streak stands at just 9 games.
- Her midnight owl tendencies are evident — the best time of day for her gameplay is precisely at 00:00 hours, when the mind apparently plays its best chess.
Whether facing down an unexpected gambit or carefully plotting positional dominance, Juliette “keopki” Cornileau continues to be a formidable name on the chessboard — both online and off. Watch out: she’s as quick with a joke as she is with a knight fork!
Hi Juliette!
You have a dynamic, tactical style that scores lots of quick wins—your miniature against awolknight (Bf7# on move 7!) is a perfect example:
What you’re already doing well
- Tactical vision: You spot loose pieces and opportunities to win material (e.g. 15.Bxa8 vs mir1970).
- Opening courage: Early central pawn breaks (d4/e5 ideas in the Philidor) show good fighting spirit.
- Decisive finishes: When the initiative is yours you can convert very fast—see your high mid-game conversion rate on .
Key areas to improve
- Time management
Five of your last six losses were on time. Bullet rewards intuition, but you are still spending ~4-7 s on many moves while opponents premove.- Build a reliable premove repertoire for obvious recaptures and checks.
- Practice “chunking” positions in puzzles so decisions become automatic.
- Play a few 3 | 2 games each day; the increment trains you to move faster without blundering.
- Early queen adventures
Several losses start with Qh5/Qd5/Qb5+ (e.g. vs myominthant7048, lforssage). Against accurate defence the queen loses tempi and you fall behind in development.- Before moving the queen ask, “Will this force a concession or simply give my opponent tempo?”
- Try the classic rule: Develop knights and bishops before bringing the queen out.
- King safety in the Scandinavian & Philidor
Games with …Qd4 or …Qd5 left your king stuck in the centre. Review these openings from a model game and aim for quick castling.- For the Scandinavian, consider the solid 3…Qa5 line instead of 3…Qd4.
- In the Philidor, remember the thematic break …d5 to free your position.
- Handling opposite-wing pawn storms
Against the KIA loss to Kiron P Mullamkuzhi you advanced flank pawns without coordinating pieces, and the counter-attack hit first.- Follow the principle “Advance pawns on the side where you are stronger”.
- Use prophylactic moves (h3, a3) before pushing major pawn storms.
Training plan for the next two weeks
- Daily 10-minute tactics set—focus on zwischenzug and forks (see fork).
- Play 20 bullet games, but annotate one each day. Look for a faster alternative in every move that took >3 s.
- Study one model Scandinavian and one Philidor game from a GM database; write the key move-order notes.
- Shadow-boxing drill: set a timer to 20 s and solve mate-in-2 positions—this builds speed without relying on premove.
